DSNU-8-20-P-A: Precision Short-Stroke Cylinder for Compact Automation
The DSNU-8-20-P-A is a double-acting round pneumatic cylinder built with a 20 mm stroke and 8 mm piston diameter, providing compact, efficient linear motion. It conforms to ISO 6432 and CETOP RP 52 P standards, with a male-threaded M4 piston rod and M5 pneumatic port for easy integration. At 6 bar pressure, it delivers a theoretical advance force of 30.2 N and return force of 22.6 N. This model includes elastic cushioning rings at both ends, ensuring soft deceleration and reducing impact stress (impact energy: 0.03 J). Made from high-alloy stainless steel (piston rod and barrel) and anodized aluminium (cover), it offers moderate corrosion resistance (CRC class 2) and supports cleanroom use up to ISO Class 6. The cylinder is also RoHS-compliant, has an ambient operating range of –20°C to +80°C, and weighs just 34.6 g (excluding stroke-related additions), making it ideal for high-speed and space-sensitive applications.
Applications of DSNU-8-20-P-A in Industrial Use
The DSNU-8-20-P-A is designed for small, precise, and repetitive operations in compact automation setups. It’s ideal for use in electronic component handling, labelling machines, test jigs, or robotic end-effectors, where controlled short-stroke actuation is required. Its lightweight design allows fast cycles with minimal vibration, while the optional proximity switch compatibility enables position tracking in smart factory systems. The cylinder is especially useful in applications like light clamping, fixture engagement, or automated part positioning where smooth, gentle movement is crucial. For Indian maintenance engineers and system designers, this model offers a perfect balance of precision, reliability, and integration flexibility in tight workspaces—making it a valuable component in micro-automation or mechatronic assemblies.
